You would expect 500 million atoms to be present. When a source experiences a half-life, it is a point in which atoms have degraded to half what they used to be in mass. 1/2(1 billion) = 500 million

Answer:
polar beacuse there is no way its non polar.
electron dot structure
Explanation:
Chemical reactions are driven by transfer or sharing of electrons between two or more atoms. To show a specie that is reactive, a sound knowledge of the distribution of electrons in the atom is necessary.
- The electron dot structure shows only chemical symbol of the element surrounded by dots which represents the valence electrons.
- The chemical symbol represents the nucleus and all electrons except the valence ones.
- The dots arranged on the four sides are called lone pairs. Those that are unpaired are called odd electrons.
- Chlorine has 7 valence electrons in its outermost shell.
- It is made up of 3 lone pairs and 1 odd pair of electron.
- The odd pair accounts for the reason why chlorine is very reactive.
- It will only require just one electron to join the odd pair so as to complete the octet and be like the noble gases.
